MWC Depthmaster - it's a tall, heavy thing and has taken some brutal whacks, so far unmarked. I did knock the lume triangle out of the previous one, but somewhat to my amazement MWC replaced the entire watch FOCC when I approached them for a replacement bezel!
Truth is though, it's not the watch when stuff like this happens - it's me, usually after a bad night without sleep or when the proverbial one-or-two light ales has been partaken-of...
